Me and my friend were arguing Borg and Federer. I told him today's game is simply just more demanding than it used to be. Players today are much more physical. They're faster, stronger, more flexible, swing harder. Any of today's players would beat any of the players from the 60's. I went on to argue that if I played Macenroe I could compete. Maybe get a few games or make it close. So, if anyone knows Macenroe or if Macenroe reads this write back.
